Can Lambda not working Link G4x on Toyota Altezza 3SGE BEAMS

[David Mejicano]

Install the Ecu Link g4x in my Toyota Altezza, install the can gauge and the can lambda, both connected on the same can bus.

All the configurations were made in the software to be able to detect the can lambda AFR and the can gauge, the can gauge began to work and then the lambda but when finishing the configurations the lambda stopped working

I already connected only the lambda AFR on the can bus and it does not work, and the can gauge only and that one does work, and when connecting both they both stop working.

We already checked all the connections and everything seems to be connected, everything seems to be that the Can Lambda is defective, any help to get it to work?

Can you attach a copy of your tune and a short log with it running.

Hello, here I leave the tune that my car has.

You have a lot of errors showing on CAN 1.  That and the fact you say the gauge doesnt work when the lambda is plugged in would suggest either the bit rate has been changed on the lambda or the CAN H/L are reversed.

Can you unplug the gauge so that only the CAN lambda is connected, then change the bit rate to 500K and try "find devices" again.  Try at 250K, 125K & 100K also to see if it gets detected at any speed.  If it doesnt detect at any bit rate, can you then unplug the CAN lambda and with ignition switch on measure the voltage between the ground wire and CAN L and the ground and CAN H then report back what you get.
